Talk:Parietal lobe

I removed this

Dr. Andrew Newberg in his research into brain activity of contemplatives and mystics suggest that the change in activity in this this area for individual in meditative states appears to be correlated to a surrendor of the sense of self or ego into something larger than self or beyond self.

I checked out the webpage. It seemed rather dubious. JohnJohn 02:16, 9 March 2006 (UTC)Reply

Hiyah,

He seems to have published quite a lot of articles in academic journals. The articles that focus on religion/spirituality and neruobiology tend to turn up in the journal Zygon which is a peer-reviewed jounal published by Blackwell Publishing. Its editorial board tends to be heavy on academic theologians, but the basic aim of the journal is to open and maintain a dialogue between science and religions. But he has also published in journals such as 'Neurological Sciences' and 'Diagnostic Nuclear Medicine'.

A quick read of some of his articles shows that he is quite rigourous in his approach to examining the neurobiological processes that underlie particular aspects of religious experience.

So, all in all, while his picture may make him look a little shonkey, I don't think that his research itself is dubious.

Ideally the sentence that was excised would be put back in, but have the links replaced with references to the research as published in a peer-reviewed journal. This article from New Scientist, 2001 was where I first read about his research: http://www.arn.org/docs2/news/searchofgod042301.htm Yvain 12:42, 14 May 2006 (UTC)Reply

I don't want to start an edit war here. I'm going to go to the literature and find studies that examined the firing of neurons in parietal cortex and will insert what I find and the references into the article. digfarenough (talk) 13:22, 21 April 2007 (UTC)Reply

I'm pretty sure the bottom picture of a brain is a monkey's brain. May want to clarify that to the world... —Preceding unsigned comment added by 67.169.37.100 (talk) 06:18, 12 August 2010 (UTC)Reply

All the pictures in the article are of human brains -- I just checked to make sure. Looie496 (talk) 22:24, 12 August 2010 (UTC)Reply

... Is this worth adding to the article? http://download.cell.com/current-biology/pdf/PIIS0960982210012340.pdf?intermediate=true It's pretty cool, if you electrocute it it makes your maths ability increase.

The paper is pretty cool but it might be a bit early to add it to the article. "Electrocution" is not the right word, by the way -- it means execution using electricity. Looie496 (talk) 17:05, 5 November 2010 (UTC)Reply

The rotating diagram of the brain is a great idea, but our perceptual system is designed to pay attention to movement, so the rotation is a constant source of distraction when reading the article text. For this reason, the user should be able to stop the rotation. This observation applies to animation inserts in all articles, including the articles on the four cerebral lobes: frontal, parietal, occipital, and temporal.

I agree, but to the best of my knowledge it is not technically possible to do that. If you would like to remove the animations (here and in the other articles where you made similar comments), you have my support. Looie496 (talk) 04:34, 16 January 2012 (UTC)Reply

If anyone knows if this article is a current classroom assignment, can they please let me know so I can be in contact with the person assigning it? I could provide useful advice, as I've done for this class: User:Biosthmors/Intro Neuro. Thanks. Biosthmors (talk) 19:59, 10 December 2012 (UTC)Reply

Just a heads-up: substantial content was deleted in March 2014 without explanation and without anyone noticing. I reverted to the version prior to the deletions. Edits subsequent to those deletions appear to be bot or minor syntax fixes, so I did not bother to re-instate them. -84user (talk) 17:23, 26 May 2014 (UTC)Reply

Right now, the article states: ″This lobe is divided into two hemispheres—left and right. The left hemisphere is involved in symbolic functions in language and mathematics. Meanwhile, the right hemisphere is specialised to carry out images and understanding of maps (i.e. spatial relationships).″

I added a citation needed flag for now, but the content seems to conflict with this article, which is well cited. Should we remove the content from this website as it is misleading? Thanks, CdavM (talk) 03:14, 12 January 2015 (UTC)Reply

I have now removed the conflicting content. CdavM (talk)

The parietal lobe's somatosensory processing is limited to providing the internal map of the external body (the sensory homunculus). This is the source of locating proximal (on you) stimuli and as feedback for motor cortex directed "Actions" directed, again, "on you."

While this may gloss to some as Navigation, it is navigation of the homuncular space not the external environment which is the canonical meaning of the word, and the function of the Hippocampus/Medial Temporal lobe. The posterior parietal cortex which serves as the Dorsal Stream "Where" or "Action" work-space in bottom up perception (in contrast to the lateral temporal Ventral stream), again serves to integrate homuncular actions, but now in a multisensory map that binds an objects' audiovisualmechanical cues for appropriate homuncular perception for action. Navigation, in contrast is concerned with movement with respect to spatial landmarks and barriers (walls etc.), which are distal and invariant to proximal action.

Similarly, having a multisensory homuncular (proximal) map/space is NOT proprioception. The homunculus is strictly the space through which proximal actions are coded. Proprioception is in fact independent and processed by the adjacent posterior cingulate with help from the insular cortex (also adjacent). The distinction here is subtle but critical, the posterior parietal space cannot distinguish action authorship, so if its action or re-action its coded the same, adding the "self" part is seperate. Furthermore, the "rubber hand illusion" (self-visually linked to not homuncular space) out of body experiences (self linked to navigational space), and hypnotic states (e.g. dreaming, disembodied self) cleanly separate homuncular processing from self, i.e. proprioception. While the posterior parietal often contributes essential information to the cause of proprioception, it is neither necessary or sufficient for it. This level of processing is strictly concerned with maintaining functional access to the external proximal world. — Preceding unsigned comment added by 50.79.55.220 (talk) 06:57, 12 April 2016 (UTC)Reply

I believe the functions of the parietal lobe are generally thought to be somewhat broader than the way you describe them. It doesn't just handle the body, it handles the relationship of the body with objects around it. for example one frequently described consequence of parietal damage is that when a person tries to pour water from a pitcher into a cup, the water misses the cup because the person is unable to align the pitcher properly. A common way of stating it is that the parietal system encodes space "egocentrically" (in body-centered coordinates) whereas the hippocampal system encodes space "allocentrically" (in body-independent coordinates).
